New research on an Australopithecus fossil called "Little Foot" helps us better understand how these ancient hominins lived. The findings suggest that this specimen could climb and move in trees as well as on the ground.
An international research team led by scientists from the U.S. and Spain, supported in part by The Leakey Foundation, has discovered a nearly complete cranium of an early human ancestor, estimated to about 1.5 million years ago, and a partial cranium dated to about 1.26 million years ago, from the Gona study area in Ethiopia’s Afar State.
Human beings used to be defined as “the tool-maker” species. But the uniqueness of this description was challenged in the 1960s when Dr. Jane Goodall discovered that chimpanzees will pick and modify grass stems to use to collect termites. Her observations called into question homo sapiens‘ very place in the world. Since then scientists’ knowledge of animal tool use has expanded exponentially.
